The beta has since been formally confirmed by Respawn’s Vince Zampella, and although we now know the test will include both Xbox One and PC, the start dates haven’t been officially announced (despite the fact that the posters pointed out February 14th) – from Zampella:

#supersecret announcement time. I'm sure no one has been able to guess from the leaks. PC and XboxOne Beta! Details in the coming days

It’s additionally been revealed that Bluepoint Games (a studio formed from game industry veterans from Metroid developer, Retro) will be handling the Xbox 360 version of Titanfall – a sliver of information that has remained secret since the announcement of the game.

Work that you might know Bluepoint from in the past include the high definition ports of games included in the Metal Gear Solid HD Collection, God of War Collection and Ico & Shadow of the Colossus Collection, as well as the PS Vita version of PlayStation All-Stars Battle Royale.
